The A111 Halogen Light Source is used in investigations of photosynthetic oxygen and carbon dioxide exchange. It radiates broad-spectrum white light (50W) . It requires AC power and cannot be used in the field. The Halogen Light source produces a significant amount of heat load. When using it as a light source above a leaf chamber, ensure that a cooling water bath sits on top of the leaf chamber to absorb the heat.
